nor-Binaltorphimine dihydrochloride is a potent and selective κ opioid receptor (KOR) antagonist[1]. nor-Binaltorphimine dihydrochloride can block the binding of endogenous ligands to KOR, thereby regulating pain perception, emotions and addictive behaviors[2, 3]. nor-Binaltorphimine dihydrochloride can reduce morphine withdrawal symptoms and the resulting conditioned place aversion in rats[4].
In vitro, treatment of rat pheochromocytoma cell line PC12 cells with nor-Binaltorphimine dihydrochloride (100nM) for 10min reversed the inhibitory effect of U-69593 (κ-opioid receptor agonist) on nicotine-induced increase in tyrosine hydroxylase (TH) enzyme activity and TH mRNA level[5].
In vivo, nor-Binaltorphimine dihydrochloride (2mg/kg) was intraperitoneally injected into hyperlipidemia model mice, blocking the normalizing effect of U50488H on mouse endothelial ultrastructure and function, inhibiting U50488H-induced increase in Akt/eNOS phosphorylation, increase in serum/medium NO levels and enhancement of eNOS activity, and also blocking the inhibitory effect of U50488H on iNOS activity[6].

Cell experiment [1]: | |
Cell lines | PC12 cells |
Preparation Method | Experiments were initiated by replacing the medium with HEPES-buffered Krebs buffer containing various concentrations (10nM–1μM) of U-69593 or U-69593 (1μM) in the presence of nor-Binaltorphimine dihydrochloride (100nM), and the cells were incubated at 37°C for 10min. Then, cells were homogenized in 0.25M sucrose (50 volumes) using a glass tissue grinder, measurement of tyrosine hydroxylase (TH, a rate-limiting enzyme in biosynthesis of catecholamine) enzyme activity. |
Reaction Conditions | 100nM; 10min |
Applications | Nor-Binaltorphimine dihydrochloride reverses the inhibitory effect of U-69593 (a κ-opioid receptor agonist) on nicotine-induced increases in tyrosine hydroxylase (TH) enzyme activity. |
Animal experiment [2]: | |
Animal models | Sprague Dawley rats |
Preparation Method | Sixty male 8-weekold Sprague Dawley rats were randomly divided into six groups: normal diet group (ND), high-fat diet group (HFD), high-fat diet+saline group (HFD+V) (0.3mL saline was intraperitoneally (i.p.) injected every 2 days), high-fat diet+U50488H group (HFD+U) (1.25mg/kg U50488H was i.p. injected every other day), high-fat diet+nor-Binaltorphimine dihydrochloride group (HFD+N) (2.0mg/kg nor-Binaltorphimine dihydrochloride, was i.p. injected every other day), high-fat diet+U50488H+nor-BNI group (HFD+U+N) (2.0mg/kg nor-Binaltorphimine dihydrochloride was i.p. injected and 1.25mg/kg U50488H was i.p. injected 10min later every other day). ND group received a regular chow diet and all other groups received a high-fat (5% cholesterol supplemented) diet. |
Dosage form | 2mg/kg; i.p. |
Applications | Nor-Binaltorphimine dihydrochloride blocked the normalizing effects of U50488H on endothelial ultrastructure and function under hyperlipidemic conditions. nor-Binaltorphimine dihydrochloride inhibited the U50488H-induced increase in Akt/eNOS phosphorylation, serum/medium NO levels, and enhanced eNOS activity. In addition, nor-Binaltorphimine dihydrochloride blocked the inhibitory effect of U50488H on iNOS activity. |
